Yes it's a real comic and yes it's different. The original crossover had various characters clashing...this one featured combinations of various characters.

most of them look just..wrong anyway did the characters somewhat got fused in the story or they are just entirely new characters based on marvel+dc? flash + captain america would basically mean just mixing the costume's colors

IIRC there was a whole storyline where the DC and Marvel universes somehow combined and for some reason all the heroes had to fight each other for the survival of their worlds. They all ended up getting amalgamated in the end. I think thats how it went anyway. Its been a long time since I read it.
